Filtration apparatus

Abstract

A filtration apparatus comprises a tiltably mounted container having a liquid permeable filter bottom, a wall opposite such bottom, and an inverted neck extending inwardly from that opposite wall. A power shaft extends through the inverted neck into the container and carries a mixing implement in the container. A guide bearing for the power shaft is located in the inverted neck. A drive for the mixing implement is supported on the container wall opposite the filter bottom for driving the power shaft. A lifting mechanism connected to said power shaft is also supported by that opposite wall for axially displacing the power shaft and mixing implement in said container. A support bearing at one side of the container and the frame has an apertured part rotatable with the tiltable container. Conduits are conducted through the apertured part for angular movement with the container, thereby avoiding a tangling of lines.

We claim: 
     
       1. Filtration apparatus comprising in combination: a container having inlet and outlet means, and a liquid permeable filter bottom situated between said inlet and outlet means;   mixing means including a power shaft extending into said container from a side opposite said bottom and carrying a mixing implement in the container, a drive for said power shaft and a lifting mechanism for axially displacing said power shaft;   a supporting frame;   means for tiltably mounting said container, including a support bearing at one side of said container and said frame, including several roller elements and an inner roller engaged by said roller elements, said inner roller having spaced-apart apertures; and   conduits leading through said spaced-apart apertures in said inner roller to and from said container for angular movement therewith.   
     
     
       2. Filtration apparatus comprising in combination; a tiltably mounted container including inlet and outlet means, and having a liquid permeable filter bottom situated between said inlet and outlet means;   mixing means including a power shaft extending into said container from a side opposite said bottom and carrying a mixing implement in the container, a drive for said power shaft and a lifting mechanism for axially displacing said power shaft;   a tilting mechanism for said container including a planetary gear; and   stepless means connected to said container for arresting said tiltably mounted container in any tilted position, including a locking brake with an automatic locking device in said planetary gear for the setting and maintenance of a specific angle of tilt.   
     
     
       3. Filtration apparatus as claimed in claim 8 or 12, wherein: said tiltably mounted container has a wall opposite said liquid permeable filter bottom, and a neck extending inwardly from said opposite wall; and   said power shaft extends through said neck into the container and has a guide bearing in said neck;   said drive being supported at said opposite wall for driving said power shaft; and   said lifting mechanism connected to said power shaft being supported by said opposite wall for axially displacing said power shaft and mixing implements in said container.   
     
     
       4. Filtration apparatus as claimed in claim 1, wherein said neck of the container has a hole at its lower end through which said guide bearing extends. 
     
     
       5. Filtration apparatus as claimed in claim 1, wherein said neck of the container has a plane surface extending transversely to a longitudinal axis of said power shaft, and said guide bearing has a collar abutting said plane surface from the inside of the container for an attachment of the guide bearing to said neck. 
     
     
       6. Filtration apparatus as claimed in claim 5, including a static seal at said collar. 
     
     
       7. Filtration apparatus as claimed in claim 1, wherein said lifting mechanism has hydraulic cylinders attached to said opposite wall and a cross beam connected to pistons of said hydraulic cylinders and mounting said power shaft. 
     
     
       8. Filtration apparatus as claimed in claim 1, wherein said drive has a geared motor connected to said opposite wall by a bearing ring. 
     
     
       9. Filtration apparatus as claimed in claim 8, wherein said bearing ring has apertures through which inlet and outlet lines to and from the inside of said neck of the container are insertable. 
     
     
       10. Filtration apparatus as claimed in claim 1, including a stationary cover extending over part of said inner roller and being connected to said frame. 
     
     
       11. Filtration apparatus as claimed in claim 2, including a hydraulic motor as a power unit for the planetary gear. 
     
     
       12. Filtration apparatus as claimed in claim 1 or 2, including an indicating device for indicating the angle of tilt of the container. 
     
     
       13. Filtration apparatus as claimed in claim 2, including means for mounting the container in the frame for a tilt up to 360°. 
     
     
       14. Filtration apparatus comprising in combination: a tiltably mounted container having inlet and outlet means, a liquid permeable filter bottom situated between said inlet and outlet means, a container wall opposite said filter bottom, and a neck extending inwardly from said container wall and having a lower end inside the container, said neck having a plane surface with a hole at said lower end extending transversely to a longitudinal axis of said downwardly extending neck; and   means for mixing materials in said container, including a power shaft extending through said neck into said container and carrying a mixing implement in the container, a guide bearing for said power shaft, said guide bearing extending through said hole at said lower end of the neck and having a collar abutting said plane surface from the inside of the container, means for attaching said collar to said neck from the inside of the container, a drive for said power shaft having a motor flanged directly to said container wall, and a lifting mechanism connected to said power shaft and supported by said container wall for axially displacing said power shaft and mixing implements in said container, said lifting mechanism having hydraulic cylinders attached to said container wall and a cross beam connected to piston rods of said hydraulic cylinders and mounting said power shaft.   
     
     
       15. Filtration apparatus as claimed in claim 14, wherein: said neck is hollow; and   said motor is flanged to said container wall by a ring structure having apertures leading to and from said hollow neck from and to the outside of said container.
